Well I changed the package type to variable and the 16 ounce item going to Great Torrington, Great Britain, Devon with a postal code of EX38 8BT rated at $16.00 but still showed the same error as above "undefined: Please enter a valid weight in ounces". The package also is set for a package dimension in inches

Units of measurement:

Length:15

Width:15

Height:2

I went to the regular USPS rate calculator and a 16 ounce package to great britain rated at $20.00 Priority international and $10.40 First Class International. Not sure if the package is actually rating correctly now. Does the fact that it is variable make that much of a difference in rating and why does not the USPS site offer these options? Or is it that the package has a clear dimension description in Uber Cart and the regular online rate calculator does not give this as an option to me to enter physical dimensions for a package. Still confused, if this rating is correct I can live with the error but I think it may scare away a potential customer. My host service still has not updated the PHP on my site server yet also because I am still getting errors in a red box from Drupal that I mentioned in an earlier post. Help please, thanks Eric
